Metal Lubricants

I can't speak so much for robot chains but I can tell you that you should absolutely never lubricate a bike chain with WD-40. It will strip any existing lubricant from the chain and leave you with metal-on-metal. Not to mention that it will leave behind a paraffin residue that will muck up with dust and dirt faster than any other product. The only time you can use WD-40 on a chain is if you're trying to clean rust off it, after which you should de-grease and clean it and then properly lubricate it.
